Pokémon Fusions

While fusion (the physical combining of two pokémon into a single unit) is very popular among the pokemon fandom, and numerous tools for fusing pokemon and fanart of fused pokemon exist, it is a rare (but not unknown) event in the core Pokémon series. Despite its overall rarity, there are enough examples of fusion in the core Pokémon series to include the idea as canon. Here are only a few of them:

  • In Pokémon Red and Blue, Bill (a human) becomes trapped in the body of a Pokémon (specifically represented by a Clefairy sprite) during an experiment with a teleporter.
    • “Hiya! I’m a Pokémon… …No I’m not! Call me Bill! I’m a true blue Pokémaniac! Hey! What’s with that skeptical look? I’m not joshing you, I screwed up an experiment and got combined with a Pokémon!”
  • Numerous pokémon are described in cannon as evolving by fusing with other pokemon:
    • According to their pokédex entries (and the Anime), Slowpoke evolves into Slowbro or Slowking by being bitten by a Shellder (on the tail or head respectively).
    • Likewise in Pokémon Red and Blue, Weezing’s pokédex entry reads: “Where two kinds of poison gases meet, two Koffings can fuse into a Weezing over many years.”
    • In Pokémon Ruby and Sapphire, Metang’s pokédex entry reads: “When two Beldum fuse together, Metang is formed. The brains of the Beldum are joined by a magnetic nervous system. By linking its brains magnetically, this Pokémon generates strong psychokinetic power.”
    • Other notable examples include: Diglet —> Dugtrio, Magnemite —> Magneton, Honedge —> Duoblade.
  • The original development artwork for Pokémon Ruby and Sapphire included a pokémon that is clearly a blend of both Blaziken and Latias (referred to as Latiken by fans). Shown below.
  • In Pokémon Black 2 and White 2, the legendary Pokémon Kyurem can be combined with either Reshiram or Zekrom using an item known as a DNA Splicer, gaining increased power and access to the signature abilities and moves of those pokémon. In those games, the process is referred to as “Absofusion”.
  • In Pokémon Sun and Moon, the Aether Foundation leader Lusamine becomes “merged” with the ultra-beast Nihilego.
  • In Pokémon Sun Ultra and Moon Ultra, the legendary Pokémon Necrozma is able to absorb either Solgaleo or Lunala gaining increased power, different typing, and access to the signature moves of those pokémon.
  • In Pokémon Duel pokémon are leveled up by combining one pokémon with another. This does not change the form of the pokémon, but effectively destroys one “donor” pokémon to give its total XP to the target pokémon. Fusing two pokémon of the same type grants a “chain level” increase in addition to the XP transfer, which can be used to improve the recipient pokémon’s moveset. Pokémon can also be fused with “rare metals” to further increase their XP level.
  • In the Pokémon Adventures manga chapter “The Winged Legends”, Team Rocket uses a Fusion Machine to merge Articuno, Zapdos, and Moltres into a single legendary bird Thu-Fi-Zer.

With all of these examples, it is clear that fusion is a canon part of the Pokémon world, but has been unable to be fully explored within the core games. With 802 known pokémon, allowing any two pokémon to fuse results in more than 640,000 possible combinations, a nearly impossible coding task. However, thanks to the limitlessness of imagination-driven tabletop gaming, we can easily include fusions in this game!

While we have two canon examples of humans fusing with pokémon as well, we’ll probably avoid that (mostly). Likewise, there is a canon example of three pokémon fusing, but we will avoid that as well, as it creates more than 500,000,000 possible combinations.


How to Fuse Pokémon

Within the core Pokémon games, two methods of fusion are introduced. The first is via a Teleporter (Red/Blue) or Fusion machine (Duel). The second is via the DNA Splicer (Black 2/White 2 and Sun Ultra/Moon Ultra).

The Fusion Machine in the later Pokémon Duel game can be reasoned to be a direct continuation of the initial research and teleporter malfunction that fused Bill with a pokémon. Both devices are shown in the games to be large, bulky, and stationary — taking up nearly half a room. These types of large devices have the advantage of being accessed controlled, allowing the DM to limit at what point in the game, and how often, fusions are made available. Because the “teleporter accident” was directly related to Bill’s creation of the Pokémon Storage System, it is reasonable that Fusion could be added as an additional function of the main storage system, should broader access to Fusions be desired. Thus Fusion Machines (where found) will be the primary method of performing fusions within this game.

The DNA Splicer, being a unique Key Item in the core games can also be used as a findable one-shot item, for those cases where Fusion would be desirable, but access to a Pokémon Center is difficult. It could also be used for unique situations, such as the fusions of Kyurem in the core games, which do not strictly adhere to the Fusion rules laid out below.

Statistics of Fused Pokémon

Images of Fused pokémon can be found using the Pokémon Fusion Generator, or by doing a quick Google image search (thanks to copious fan-art), or by flexing your own photoshop skills.

When combining two pokémon of the same species (i.e. two pikachus) the trainer must choose one of the two pokémon to be the donor, and the other to be the recipient. The donor pokémon is lost, and the total experience points and EVs of the donor pokémon is added to the experience and EVs of the recipient pokémon. Other than this increase in total experience (and thus level), no other changes are accrued from fusing two pokémon of the same species.

When fusing two pokémon of different species, the statistics of fused pokémon are determined as follows:

  • The Type of the fused pokémon is equal to the primary type of the two pokémon being fused (thus a Butterfree which is Bug/Flying and a Pidgeot which is Normal/Flying would result in a pokémon that is Bug and Normal type). If both pokémon share the same primary type, then the new pokémon will inherit the secondary type of one of the two pokémon (chosen by player).
  • Base Stats are equal to the Sum of the base stats of the two pokémon species being fused, times 0.55, and rounded down to the nearest whole number1.
  • IVs are equal to the Sum of the IVs of the two pokémon, divided by 2.
  • EVs and experience are equal to the SUM of the total EVs and experience of the two pokémon.
    • The new pokémon’s level is determined based on the new XP total using the slower Experience Table of the two pokémon being fused (thus a Ducklett which uses the Medium Fast chart, combined with a Breloom which uses the Fluctuating chart, would use the Fluctuating chart to determine it’s new level).
    • As per usual, the EVs of the combined pokémon cannot exceed 252 for a single stat or 510 in total.
  • The Nature of the new pokémon are determined by taking the sum of the numerical value of the two natures and dividing by 2 (round fractions down). Thus a Jolly pokémon (nature #13) combined with a Brave pokémon (nature #2), would have a Relaxed nature (nature #7).
  • If either of the fused pokémon has a Signature Ability, the new pokémon will possess that ability. Otherwise the new pokémon may have the ability of either original pokémon (player’s choice)2.
    • If both pokemon being fused possess a Signature Ability, the ability of the fused pokemon is selected randomly from the two.
  • The fused pokémon will know any 4 moves from among those currently known by either original pokémon (player’s choice). As the fused pokémon advances, it can learn any moves available to either of its donor pokémon either through level up (at the same level as the donor pokémon) or through TMs or tutors.
  • If either original pokémon is still able to evolve, the fused pokémon will not evolve as part of the fusion (even if the level calculated according to its new experience total would be high enough to evolve). The new fused pokémon will be able to evolve into a fused form of its next stages at the same level(s) that its constituent pokémon would evolve.

A pokémon that is created by the fusion of two pokémon of different species cannot be further fused. Though is may be fused to gain XP and EVs with another pokémon of the same fused species (it no longer counts as its constituent species for experience fusing).


1 The two canon examples of fusion in the games (Kyurem and Necrozma), both have higher base-stat totals than the average of the pokémon being combined. Thus fusion results in a being slightly greater than the sum of its parts.

2 Both canon examples have the fused pokémon taking on the signature ability and moves of the pokémon it is being fused with. Also, this means that player’s cannot abuse fusing things with Slaking and hoping to get its massive Attack power without Truant.
